Working Theory

Magnum Vespa Beverly 250 ie. Oxygen Sensor Simulator is a must-have tuning device if you installed aftermarket pipe, or heavily tuned-up the exhaust in any way, on your emissions-controlled motorcycle or trike. The modified engine now produces a larger amount of exhaust gases than allowed. When the exhaust air fuel sensor delivers the Powertrain Control Module a signal that is not within the manufacturer's specifications the OBD-II (OnBoard Diagnostic) system logs an error, accordingly warning light will illuminate, resulting in Engine management safe mode and reduced performance at the wheel. Heated Motorcycle Vespa Beverly 250 ie. O2 Sensor Simulator is an add-on replacement wired up to the post o2 sensor harness. It supplies the Electronic Control Unit with mimic, fluctuating voltage signal and fools the Engine computer thinking the emission is normal. This Vespa Beverly 250 ie.oxygen sensor simulator will allow you to run with your exhaust upgrades and still keep the engine management warning light off.

When warning light is triggered, engine turns into limp mode causes the engine run less efficiently both performance and fuel efficiency wise. This Heated Motorcycle Vespa Beverly 250 ie. O2 Sensor Simulator eliminates your oxygen sensor without any compromise of performance or fuel efficacy. Magnum Oxygen sensor simulator available to all bikes on which the emissions are monitored through air fuel sensor. This product remedies all exhaust related ECU codes caused by aftermarket exhaust. Dual exhaust with two oxygen sensors needs two units. Our digital Vespa Beverly 250 ie. O2 Sensor Simulator is adjustable, allowing you to adjust the Air / Fuel Ratio within certain range is yet accepted by the ECM. You can now eliminate the stock air fuel sensor completely and ride without miffing service light cause the engine run in safe mode.

Note

This bike Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not street legal in several US states and countries.

Questions and answers

Can I be positive this chip fixes my CEL issue for good and all?

Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor related codes will be gone.

What if I simply eliminate factory oxygen sensor?

Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code

Why is it so important to cancel the trouble code?

While check engine light is on, ECU restricts the engine performance and vehicle is running in safe / limp mode. MPG is also affected negatively.

Do I need to buy this heated simulator or I can stick with cheaper EZ CEL Fix?

If you can use the heater of the factory oxygen sensor(s), you may wire up #796 EZ CEL Fix. This heated simulator #664 allows you to remove or eliminate the stock oxygen sensor completely.

What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems?

The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them doesn't take effect on OBDII vehicles made after 1996. They often don't work even on early fuel injected cars. If your vehicle had been manufactured after 1996 or you drive an early model controlled by a sensitive ECU, these gadgets won't help. The definite solution is a circuit conditions realistic signal, as if a working oxygen sensor would be screwed in the factory exhaust.

Can I rally my two harnesses into one simulator?

No, simulators can't be spliced.

Get rid of oxygen sensor related CEL issue yet today. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when modifying an exhaust. You might be interested in our further performance chips in order to boost engine horsepower, improve fuel efficiency or both at the same time. EVO-Tech, Dyno-Boost and Smart-Tune-X fuel controllers remap the ECU in order to reprogram the engine management to the performance parts preinstalled on the vehicle. They boost the engine horsepower as well as improve fuel mileage. Magnum Tuning has been dealing with manufacture of performance upgrades since 1994. Our experience warrants peak performance, reliability perfect style. Parts are made in Europe covered by 10-year warranty. Not quite sure this oxygen sensor eliminator fits your needs?

Wiring

Cut the harness of the oxygen sensor.

See colors operations of each wire in motorcycle wiring diagram or search for your combination in the table below.

Connect the proper wires with terminals or solder them in place. (Hydrochloric acid recommended if soldering.)

Contact the red cable of the red/black dual wire to the ignition feed + 12V, and the black to the engine frame or battery negative.

Mount the unit to any fixture as far from heat as possible. Lowest temp recommended.

No heater test required in case of 2-wire sensors.

Heater adjustment

Heater adjustment is required if heater related CEL code is tripped after installation. This is not uncommon.

Heater dial can be determined with an Amper-test.

Take a multi-meter and turn it to AMP mode.

Contact the stock sensor's one wire to the battery negative terminal, the red lead of multi-meter to the battery positive and black lead to the other heater wire.

Wait 10 seconds until heater warms up (cold and hot amp readings differ) and check the AMP reading. Take note of it.

Repeat the same test with the simulator and set the same AMP reading by dialing screw#2. Wire up simulator’s heater wires to the vehicle’s heater harness afterwards.

Although Magnum O2 Sensor Simulator makes you enable to adjust the air fuel ratio within a certain range, basically it is not intended to remap the fuel trim. If you are about to override the factory lean fuel programming or you want to optimize the potential of your exhaust upgrade, feel free to check out our fuel controllers .

Oxygen sensor eliminator has to be powered on ignition feed DC 12V. Never connect hot wire to constant battery voltage. This wiring may lead to battery drainage also may fry the circuit.

Smog test result depends on the criteria of your local emissions inspection. Simulator is neither supposed to improve emissions spoiled by an aftermarket pipe or any other upgrade, nor restore factory emissions required for a smog inspection. It is solely intended to help you get rid of ECU safe mode triggered by check engine light issue. It will not allow you to preserve factory emissions level. Simulator tricks the computer delivering mimicked signal is accepted by the ECU but it can’t purify the fume electronically. Cat is intended to attain that physically. Even though restoring of ECU to normal mode from safe mode improves emissions partially, if converter is gutted, worn or defective, original emissions can be preserved by no means.

The simulator is waterproof but not submersible.

Oxygen sensor simulator's signal is set to factory 0.9…0.95V top voltage. Don't adjust signal related screw#1 until CEL issue is resolved. Basically screw#1 should not be dialed unless you want to modify air fuel ratio. We don't bear responsibility for CEL shut down, if signal is not set to the top voltage above.
